Effect of Seed Stimulation Treatments with Hydrogen Peroxide and Sowing Dates on Growth Traits of Sorghum Cultivars

Abstract In the spring of 2023, researchers from the Agricultural Research Department of the Ministry of Agriculture in Abu Ghraib conducted a field experiment on their agricultural lands. Examining how different Sorghum cultivars’ growth properties were affected by hydrogen peroxide seed stimulation treatments and planting dates was the main objective of this research. A three-replica, three-factor Randomized Complete Block Design (RCBD) was used to arrange the experiment with split-plots. On 11/3/2023 and 25/3/2023, the primary plots were assigned for planting. Al-Khair, Buhooth - 70, and Rabih were the three white corn kinds that were planted in the secondary plots. In the tertiary experiments, a 9 ml l -1 concentration of hydrogen peroxide was used to stimulate the seeds. Two control groups, one priming the seedlings with just distilled water and the other with dried seeds, were also included. In terms of average growth qualities, the results demonstrated that sorghum seeds stimulated with distilled water produced the best outcomes. All growth attributes averaged out best on the 25/3/2023 planting date. Rabih cultivar outperformed the other varieties in traits of chlorophyll content, leaf area, and plant dry weight. The interaction of seeds stimulated with distilled water and planted on 25/3/2023 showed significant superiority in traits chlorophyll content, leaf area, and plant dry weight. Rabih seeds stimulated with distilled water give the highest averages for the all studied traits.
